condensing boiler formula

Chapter 5: Residential Furnaces and Boilers Evaluation

Thus, for the most efficient boilers (usually condensing units), it is not valid to assume the approximation of the ratio of rated peak input to output capacities is proportional to the AFUE. This difference carries implications regarding which formulas can be used to calculate savings.
